I have been hoping to shake some hidden benefits out of this skill, but no luck so far. I tried using Precise Shot and Longarm as openers with a sniper rifle and an optical bracelet equipped and more Stealth Power than Ranged Power. I have not noticed any changes in combat messages or anything else out of the ordinary, even when I kill my opponent with just the opener and don't chain for maximum sniper-y one-shot-one-kill-ness. If there's a special Sniper Shot technique hiding somewhere, I'm out of ideas for finding it.
